SPINNING-MACHINE.

Application filed March 14, 1910.

T 0 all whom it may concern:

Be it known that I, EZRA DIXON, a citizen of the United States, residing at Bris tol, in the county of Bristol and State of Rhode Island, have invented a new and useful Improvement in Spinning-Machines, of i I the slot in the screw 4 and the same is then revolved until the desired adjustment is which the following is a specification.

This invention has reference to an improvement in spinning machines and more particularly to the weight levers of spinning machines.

In spinning machines pressure is exerted onthe drawing rolls by means of the top roll saddles, stirrup strap and weight lever. Under the varying conditions of the roving the common practice is to move the weight on the weight lever to vary the pressure on the top rolls and the roving. In practice it has been found that for the fine adjustment of the pressure on the top rolls, itis desirable that two points remain practically the same, that is, that the fulcrum point of the weight lever be not disturbed and that the weight remain at practically a fixed point on the weight lever.

The object of this invention is to supply a means of adjusting the stirrup strap on the weight lever without disturbing the fulcrum point of the weight lever or the weight.

The invention consists in supplying the weight lever wvith a screw to whichthe lower end of the stirrup strap is secured, as will be more fully set forth hereinafter.

Figure l is a transverse section view of a spinning machine, showing my improved mechanism in operative position. Fig. 2 is an enlarged view of the fulcrum end of the weight lever partly .in section, and Fig. 8 is an end view of the weight lever.

In the drawings, a indicates the front rail of a spinning machine, 6 the roller stand, 0 c the bottom rolls, (Z d the top rolls, 6 the front top roll saddle, f the stirrup strap, 9 the weight lever, 72 the eye forming the fulcrum of the weight lever, and 7c the weight.

The adjusting mechanism consists of the screw 4 which is screw-threaded into the hub 9 formed on the front end of the weight lever. The screw 4 is formed with the groove 5 and the head 6 in which is formed the slot 7 by means of which the screw may be revolved by a suitable tool. The stirrup Specification of Letters Patent.

Serial No. 549,228.

strap f has a hole as 8 formed in its lower end through which the head of the screw 4 can be passed to seat the end of the stirrup strap in the groove 5 of the screw 4:.

When it is desired to adjust the weight on the top rolls a suitable tool is applied to reached.

It is evident that a very fine adjustment of the weight on the top rolls may be obtained by my improved device without disturbing either the fulcrum point of the weight lever or the weight.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a spinning machine, the combination with a top roll saddle and a stirrup strap, of a lever supported on said machine one end of said lever carrying a weight and the opposite end of said lever being provided with an integral hub, a screw having a groove and head, threaded in said hub so as to extend longitudinally of the lever and parallel therewith, said screw being disposed below the lever body and above the end of said lever fulcrum and having the end of said stirrup strap seated in said groove.

2. In a spinning machine, the combination with a top roll saddle and a stirrup strap, of a lever supported on said machine, one end of said lever carrying a weight and the opposite end of said lever being provided with an integral hub located above the lever fulcrum, and below the lever body, said hub being formed by enlarging opposite sides of the lever belowthe lever body and being provided with a threaded aperture, a screw having a groove and head at one end, the opposite end being screw threaded to enter the aperture formed in the hub, the grooved portion of said screw being seated in an aperture formed in said strap.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EZRA DIXON.
